Previous tuesday I sent an email to api@twitter.com asking for permission to use xAuth and reverse-auth inside our app.
I provided lots of details (including screenshots) which best describe why we need this feature in our app but we still have no news from you yet.
No emails in spam folder which I double checked.
Several days ago I tried sending another request with my other email account but we still had no answer.

This is our ticked id (copied from the auto-generated message sent by your system) #5003662
Can you please give us any info about our request or whether you need more details from us?
